Description

Technical Field

[0001] This utility model relates to the field of sandblasting mechanism technology, and in particular to a sandblasting mechanism for processing container corner fittings. Background Technology

[0002] Container corner fittings are metal components installed at the eight corners of a shipping container. They are key parts of the container, primarily serving to connect, secure, and lift it. During container stacking, transportation, and loading / unloading, corner fittings are critical components bearing various forces. During manufacturing, various impurities may remain on the surface of container corner fittings, such as scale, rust, oil, dust, and molding sand generated during casting or forging. Sandblasting can effectively remove these impurities. Sandblasting uses compressed air to create a high-speed jet that propels abrasive material at high speed onto the surface of the workpiece, altering its outer surface or shape. Sandblasting mechanisms for processing container corner fittings incorporate the following technologies:

[0003] 1. Sandblasting chamber: The outer shell of the box-type sandblasting machine is the external frame of the entire equipment. It is usually welded from steel plates. Its main function is to enclose the sandblasting operation space to prevent sand and dust from spilling out, and to protect the safety of the operators and the surrounding environment. In order to facilitate the operators to observe the working conditions inside the sandblasting chamber, the sandblasting chamber is usually equipped with an observation window. The operators can monitor the sandblasting effect on the workpiece surface in real time through the observation window.

[0004] 2. Sandblasting system: The spray gun is the core component of the sandblasting system. Its function is to mix sand and compressed air and spray it onto the surface of the workpiece at high speed.

[0005] 3. Sand supply device: The sand supply device mainly includes a sand tank and a sand conveying mechanism. The sand tank is used to store sand, and its capacity depends on the model and purpose of the sandblasting machine.

[0006] 4. Air compressor and piping: It compresses the outside air to a certain pressure and then delivers it to the spray gun through the piping.

[0007] 5. Sand recovery system: A screen is installed at the bottom of the sandblasting chamber or in a dedicated recovery area to separate sand and impurities. When the sand and impurities cleaned from the workpiece surface fall back to the bottom together, the screen will intercept impurities larger than the screen aperture, while the sand will fall into the recovery bin through the screen.

[0008] During the sandblasting process of container corner fittings, one hand needs to hold the spray gun and the other hand needs to move the corner fitting to ensure that all surfaces of the corner fitting are fully and evenly sandblasted. Due to the large size of the corner fitting, it is difficult for the user to move the corner fitting so that the spray gun can sandblast different surfaces of the corner fitting, resulting in extremely inconvenient operation and low work efficiency. This application proposes a solution to this problem: add a clamping mechanism to the body of the sandblasting mechanism. The corner fitting is fixed by the clamping mechanism. The user rotates the clamping mechanism to drive the corner fitting to rotate, thereby making it easier for the user to sandblast different surfaces of the corner fitting and preventing low work efficiency. Utility Model Content

[0009] To address the shortcomings of existing technologies, this utility model provides a sandblasting mechanism for processing container corner fittings. It solves the technical problem that the large size of the corner fittings makes it difficult for users to move them so that the spray gun can sandblast different surfaces of the corner fittings, resulting in inconvenience and low work efficiency.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] A sandblasting mechanism for processing container corner fittings includes a machine body. The machine body has a clamping mechanism inside. The clamping mechanism includes a rotating shaft, a fixed block, a clamping plate, a groove, a spring, and a moving plate. The rotating shaft is rotatably connected inside the machine body. The fixed block is fixedly installed outside the rotating shaft. The clamping plate is fixedly installed outside the fixed block. The groove is opened outside the fixed block. The spring is fixedly connected inside the groove. The moving plate is fixedly connected outside the spring.

[0012] The machine body has an internal mounting block with a rotating hole on its exterior. A rotating shaft is rotatably connected inside the rotating hole. Two threaded rods are fixedly installed inside the machine body, and each threaded rod is threaded with a nut. The two ends of the mounting block are slidably connected to the exterior of the two threaded rods. An internal groove is formed inside the groove, and an internal plate is slidably connected inside the internal groove. The internal plate is fixedly installed outside the moving plate. A rotating disk is fixedly installed outside the rotating shaft, and the rotating disk is located between the mounting block and the fixed block. Rubber pads are snapped onto the exterior of both the moving plate and the clamping plate. Each rubber pad has a fixing groove on its exterior, and the two rubber pads are snapped onto the exterior of the moving plate and the clamping plate respectively through the fixing groove.

[0013] Preferably, both the moving plate and the clamping plate are provided with adjustment blocks on their exterior, and the adjustment blocks are T-shaped.

[0014] Preferably, both the moving plate and the clamping plate have three adjustment holes on their exteriors, and the adjustment block is engaged inside the adjustment holes.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. By setting up a clamping plate and a moving plate, the corner piece to be sandblasted is placed on the screen inside the machine. At this time, the moving plate is moved upward, and the spring is compressed. The corner piece is fitted onto the outside of the clamping plate and the moving plate through its own through hole. Then, the moving plate is released. Under the action of the spring, the moving plate moves downward until it contacts the inner wall of the corner piece, clamping the corner piece on the outside of the clamping plate and the moving plate. At this time, the user holds the spray gun in one hand to sandblast the corner piece, and rotates the shaft with the other hand to rotate the corner piece or directly push the corner piece. This operation method reduces the impact of the corner piece's size, makes it easier for the user to operate, and makes it easier for the user to sandblast different surfaces of the corner piece, thus preventing low work efficiency.

[0017] 2. By setting up the mounting block and cooperating with the nut, the connection between the nut and the threaded rod is released. At this time, pulling the mounting block will release the connection between the mounting block and the threaded rod, and the clamping mechanism will be disassembled. This will prevent the clamping mechanism from affecting the entry of larger workpieces into the machine for sandblasting, and improve the flexibility of the clamping mechanism.

[0026] This application provides a sandblasting mechanism for processing container corner fittings, which effectively solves the technical problem that the large size of the corner fittings makes it difficult for users to move them so that the spray gun can sandblast different surfaces of the corner fittings, resulting in inconvenience and low work efficiency.

[0027] Example

[0028] The technical solution in this application effectively solves the problem that the large size of the corner pieces makes it difficult for users to move them so that the spray gun can sandblast different surfaces of the corner pieces, resulting in inconvenience and low work efficiency. The overall idea is as follows:

[0029] To address the problems existing in the prior art, this utility model provides a sandblasting mechanism for processing container corner fittings, including a body 1. The body 1 has an internal clamping mechanism, which includes a rotating shaft 2, a fixing block 3, a clamping plate 4, a groove 5, a spring 6, and a moving plate 7. The rotating shaft 2 is rotatably connected inside the body 1. The fixing block 3 is fixedly installed outside the rotating shaft 2. The clamping plate 4 is L-shaped and fixedly installed outside the fixing block 3. The groove 5 is formed outside the fixing block 3. The spring 6 is fixedly connected inside the groove 5. The moving plate 7 is L-shaped and fixedly connected outside the spring 6. By setting the clamping plate 4 and cooperating with the moving plate 7, the clamping mechanism can... The corner piece to be sandblasted is placed on the screen inside the machine body 1. At this time, the moving plate 7 is moved upward, and the spring 6 is compressed. The corner piece is fitted onto the outside of the clamping plate 4 and the moving plate 7 through its own through hole. Then, the moving plate 7 is released. Under the action of the spring 6, the moving plate 7 moves downward until the moving plate 7 contacts the inner wall of the corner piece, clamping the corner piece on the outside of the clamping plate 4 and the moving plate 7. At this time, the user holds the spray gun in one hand to sandblast the corner piece, and rotates the rotating shaft 2 with the other hand to rotate the corner piece or directly move the corner piece. This operation method reduces the impact of the corner piece's size, makes it easier for the user to operate, and makes it easier for the user to sandblast different surfaces of the corner piece, preventing low work efficiency.

[0030] The machine body 1 has an internal mounting block 8 with a rotating hole 9 on its exterior. The rotating shaft 2 is rotatably connected to the interior of the rotating hole 9, forming the connection between the rotating shaft 2 and the machine body 1. Two threaded rods 10 are fixedly installed inside the machine body 1, and each threaded rod 10 is threadedly connected to a nut 11. The two ends of the mounting block 8 are slidably connected to the exterior of the two threaded rods 10. By setting the mounting block 8 and cooperating with the nut 11, the connection between the nut 11 and the threaded rod 10 is released. At this time, pulling the mounting block 8 releases the connection between the mounting block 8 and the threaded rod 10, and the clamping mechanism is disassembled. This prevents the clamping mechanism from interfering with the entry of larger workpieces into the machine body 1 for sandblasting, and improves the flexibility of the clamping mechanism.

[0031] The groove 5 has an internal groove 12, and an internal plate 13 is slidably connected inside the internal groove 12. The internal plate 13 is fixedly installed on the outside of the movable plate 7. The internal plate 13 seals the groove 5 to prevent the material used for sandblasting from entering the interior of the groove 5 and affecting the use of the spring 6.

[0032] A rotating disk 14 is fixedly installed on the outside of the rotating shaft 2 to facilitate the user to rotate the rotating shaft 2. The rotating disk 14 is composed of a cylinder and a cuboid plate and is located between the mounting block 8 and the fixing block 3.

[0033] Rubber pads 15 are snapped onto the outside of both the movable plate 7 and the clamping plate 4. Each rubber pad 15 has a fixing groove 16 on its outside. Two rubber pads 15 are snapped onto the outside of the movable plate 7 and the clamping plate 4 through the fixing groove 16. When clamping the corner piece, the rubber pads 15 contact the surface of the corner piece to increase friction. Adjusting blocks 17 are provided on the outside of both the movable plate 7 and the clamping plate 4. The adjusting blocks 17 are made of rubber and are T-shaped. Three adjusting holes 18 are provided on the outside of both the movable plate 7 and the clamping plate 4. The adjusting blocks 17 are snapped into the inside of the adjusting holes 18. The adjusting blocks 17 and the rubber pads 15 are respectively attached to the two ends of the through hole of the corner piece to fix the corner piece and prevent the corner piece from moving laterally.

[0034] Working principle:

[0035] First, slide the two ends of the mounting block 8 to the outside of the two threaded rods 10 respectively. Then, thread the nut 11 to the outside of the threaded rods 10 until the nut 11 is attached to the outside of the mounting block 8. At this time, adjust the distance between the adjusting block 17 and the rubber pad 15 according to the depth of the through hole of the corner piece. That is, the adjusting block 17 and the rubber pad 15 need to be attached to the two ends of the through hole respectively.

[0036] The second step involves placing the corner piece to be sandblasted on the screen inside the machine body 1. The moving plate 7 is then moved upwards, compressing the spring 6. The corner piece, through its own through-hole, fits onto the outside of the clamping plate 4 and the moving plate 7. The adjusting block 17 and rubber pad 15 on the clamping plate 4 are then attached to both ends of the through-hole. The moving plate 7 is then released, and under the action of the spring 6, it moves downwards until the adjusting block 17 and rubber pad 15 are attached to both ends of the through-hole, thus clamping and fixing the corner piece. The user then uses one hand to hold the spray gun and sandblast the corner piece while simultaneously rotating the rotating disk 14, causing the rotating shaft 2 to rotate. The corner piece rotates accordingly, allowing the user to sandblast different sides of the corner piece. After sandblasting the corner piece excluding the clamped portion, it is removed from the clamping mechanism, and the remaining portion is sandblasted using the spray gun. The remaining portion is small and located on the same side, so there is no need to flip the corner piece.

[0037] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all possible embodiments. However, any obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
